, tivcs is conducted to the pipe C leading to heating tank R and S canbe directed into the catch basin. The pipe Q, is also provided with aconnection leading to the steam coils 6, 6, 6, 6, in the heater R, andsaid coils each being provided at one end with a valve 7, and at theother end with a check walve 8. The pipe Q is also provided with aconnection 9 leading to the steam coils 10, 10 in the tank S, such coils10 being provided with cutoff valves 11, 11 and check valves 12, 12. Theoutlet end of these coils have connection with the coils 20, 20 throughthe trap N by means of the pipes 13. The back pressure valve 15 isprovided in the pipe 25. Live steam from the stationary boiler P may bealso supplied to the steam coils in the tanks R and S by means of thepipe 18 leading to the pipe and provided with a pressure reducing valve19.- The lower heatin tank S is also provided with a pair of additionalheating coils 20, 20 which coils are provided at their inlet ends withthe valves 21, 21, and at their outlet ends with check valves 22, 22.The outlet ends of the coils are connected to the pipe 23 leading to thetrap N. The coils 20, 20, are supplied with steam from the exhaust pipes24: of the pumps K and L, and the exhaust pipe 25 of the pump M, allsuch exhaust pipes being connected to the pipe 14 leading to the coils20, 20 in the manner shown. The. water of condensation from the trap N,is forced to the wells H and O by means of the pump M, such pump beingconnected to the trap by means of the pipe 26, and to the wells H and Oby the pipes 27 and 28 respectively. Means for op erating the pump M isapplied thereto from the boiler l by means of-the pipes 18 and 29, andsteam for operating the pumps K and L is supplied from the boiler, bymeans of the pipe 30, governors 30, 30' being provided adjacent saidpumps to insure a constant and even pressure to the lines suppliedthereby.

The hot water coming from the locomothe catch basin E, by means of thepipes 31. and the flexible connections 32, such pipe members both beingconnected to the mixer 33, and the connection 32 being connected at itsinner end to the blow-off valve of the locomotive. The water from thecatch basin E passes through the pipe 34 at the well 1*, and thenthrough the filter plates G to the, filter well H, the overflow fromthese recep tacles being provided for by means of combined overflow pipeand vent 35. The filtered water in the well H may be carried directly tothe pump K by means. of the pipe 36, or if necessary can be transferredto the treatment tank I. In order to accomplish this latter result, thepump 37 operable from the electric motor 38 is provided. The

the pump K pump 37 has two suction connections with eases":

the well H, via, the pipe 39 leading to the bottom of the well for usewhen it is desired to remove all of'the water from the well H, and thepipe 40 extending only a slight distance below thesurface of the waterin the well, and designed to be normally used so that the hottest wateris re moved from the well to the treatment chamber. The pump dischargesto the treatment chamber by means oi the pipe 4d. The operation of themotor 39 is controlled by means of the float 42 connected to the switch43, which switch governs the operation of the motor. When the level ofthe water in the treatment chamber 1 falls below a certain level thefloat operates the switch to start the motor, and when the water in thetank I reaches its proper level weighted means returns the switch to ino)erative position. The pump K is supplied irom the treatment chamber bymeans of the connecting pipe 43, such connecting pipe having a hingedend le connected to the float so that the hottest water from the chamberis supplied to the pump. The outflow from takes place through the pipe44, which pipe is connected atits upper end to the washout pipe U. Thispipe U has a series of connections to the miners 33, and anotherconnection 4C6 which is not con nected to a mixer and to which a hose 46may be applied direct if desired. The Jipe 44 also has branchconnections, 4.? ano 48,

leading to the bottom and top of the tank S, that water can be suppliedto this tank, and, it desired, by closing the cook 49 in the pipe at,and opening the valves in both the pipes -17 and 48, the water forwashing out purposes may be supplied from the tank S. thus giving waterof a higher temperature. in some cases the water from the pipe 44 may beof too high a temperature and need tempering, and in order to fulfilthis requirement and maintain the water at any desired temperature, thethermostat 50 is applied to the pipe 41%, which thermostat governs avalve 51 on a pipe 52 leading from the supply main V to the pump. Thepump L is also supplied directly from the main V and is provided with adischarge pipe leading to the filling upper tank for further heatingWhen water is supplied the tanks R and S from the pump L and main V, thecoils W in the tank i constitute a secondary. feed water heating means,whereby hot water from the main is supplied heater R and S. i
